When JK Rowling speeds ahead in time to the golden trio's children's train ride, she puts a variable in time. But one little change in the variable can change the whole equation.

From The Potters: Albus Severus ,James Sirius and Lilly Luna, to Ron's and Hermione's: Rose and Hugo. Fred and Angelia's: Roxanne and Fred, plus Percy and Audrey's: Molly and Lucy also, Bill and Fluers: Voctorie, Dominque, and Luis. Let's not forget Luna, who married Newt Scamander's son, Rolf, and had Larean and Lysander. Also, Draco Malfoy and Astoria's Scorpious.
